Chemistry - Polymer Question with Solution | TestHub

Thermoplastic polymers are linear or slightly branched long chain molecules capable of repeatedly softening on heating and hardening on cooling. Examples include polythene, polystyrene, polyvinyls, etc.

Urea formaldehyde resin and Bakelite are heavily branched or cross-linked polymers, which are classified as thermosetting polymers.

Buna-N is a rubber-like solid with elastic properties, which is classified as an elastomer.

Therefore, polythene is the thermoplastic polymer.

Answer: Polythene
